You could set "Allow guests to browse the forum" to false, but then guest also cant see the boards, topics & posts.
@Nao, theres definetly a Permission missing... "View Thoughts" should really be there, sounds like a feature request :D

Just select the 'Members' group in your privacy box... All of your future thoughts will be viewable by members only by default (until you reset it). I think that thought visibility should be up to the author's discretion.
Why would you want to hide all thoughts from all guests, unconditionally..?

Hi,

"Thoughts" content links  other domain links add  rel=”nofollow” tag

thanks

I think Gevv's right and before too long the spammers will have worked out that posting a link in a thought is quicker than posting it or adding it to a signature. If guests cannot see thoughts then search engines cannot 'see' them. Guest access to thoughts should be off by default.
